Tire Facts

What Every Vehicle Owner Should Know About Tires

New Tires
  1. Underinflated tires make your engine work harder, reducing gas mileage.
  2. Radial Tires are engineered to be rotated from side to side. Even though side to side is a more common option, front to back rotation is still a viable option with the radial tires on the market today.
  3. If possible, know what type of tire was originally on your vehicle from the factory. For example, not all SUVs come with passenger tires. Some of them, like the light trucks, have the "LT" on the tires. It is always best to replace your tires with the type of tires recommended by the OEM.
  4. Underinflated tires are going to wear faster than properly inflated tires. Underinflated tires will even affect the handling and steering control the driver has over the vehicle.
  5. When the tire pressure is too low, this means that too much of the tire's surface area is touching the ground. This increases the amount of friction between the road and your tires. Due to increased friction the tire will wear out faster and could potentially overheat, possibly resulting in a "blow-out."
  6. If you notice your tires squealing when cornering, this is a sign of low tire pressure.
  7. Even though your tires don't appear to be flat, this doesn't mean they are properly inflated. Air naturally escapes from tires so consistent checking of the tire pressure should be routine tire maintenance.
  8. The leading cause of tire failure is due to underinflation. As already mentioned underinflation leads to irregular tire wear and loss of traction on the road surface.
  9. Different tire manufacturers usually test tires and assign their own grades for tread wear, traction, and temperature resistance. Tire ratings should be key elements in selecting new tires for your vehicle.
  10. Tires naturally lose air at a rate that's about a pound per month. This number can be much greater depending on the weather conditions.
  11. Underinflation, by as little as 6 psi, can cut gas mileage by 3%. It may seem like a small thing but maintaining proper tire inflation will save you money at the gas pump.
  12. Cold weather greatly affects the air pressure of tires. For every 10 degree drop in temperature tires will lose one pound of pressure.
  13. Gas mileage decreases 1% for each 10 pounds of underinflation.
  14. If you're only going to buy one or two tires at a time, you should always put the new tires on the rear axle.
  15. When you have underinflated tires you'll notice uneven wear on the outside edges of the tire. Overinflated tires will wear in the center of the tread.

The facts listed above will hopefully give you a better idea of the importance of proper tire care and tire maintenance. And of course if you need new tires, tire repair, or any expert tire advice be sure to stop by Murphy's Auto Glass & Tire Express for all your tire needs.
